The Malheur Country Historical Society serves to keep the memories of Malheur County and the surrounding area alive and bring people with this common goal together. Some of its projects include maintaining historical sites, gathering oral histories, preserving antique photos, and developing the MCHS History Book, which is full of biographies of the citizens that made and are making this area what it is today. The meetings take place in Ontario, Oregon, which is located in Malheur County. Many of the members are from all over the Treasure Valley, which is essentially a cluster of cities in Eastern Oregon and Western Idaho.

The Oregon Genealogical Society maintains a genealogical and historical research library in Eugene, Oregon for use by members and the general public alike. The OGS library has a large selection of Oregon research materials as well as over 8,000 books and 2,000 periodicals from most localities nationwide. Throughout the year OGS offers genealogical classes in a variety of subjects for all levels of experience, from the beginner to the more experienced researcher. And twice a year, in the spring and fall, the society organizes and hosts an all-day seminar featuring regionally and nationally renowned genealogical lecturers.
